I just saw a thread TonyN was helping with dated way back in 2007...
and i just wanted to check something he said as its identical to a problem my 3rd Gen has...
My rear end has been gradually getting louder over the last few years (its around 130k miles now), and its now needing a third rear axle oil seal in less than a year. A mechanic has said the wheel bearings seem ok, and that the rear diff sounds to be the source of the noise - as he ran it on the ramp with wheels removed.
My question is, in the quote below, when it states knackered bearings being the cause of oil in the rear brakes, are you meaning the rear diff bearings or wheel bearings?
and is it cheaper to buy a re-conditioned rear diff or get it overhauled?
thanks

"Its not so bad, remove the wheels, prop and drain the oil. Then undo the brake cables and pipes from the brake back plates. Then undo the 4 nuts holding them to the axle housing and pull the shafts and backplates out about 3-4"s (you need to get the shafts out from the spider gears)
Then you can undo the diff bolts and pull it out. You might have to move the ARB to get the diff out, you have to on 2nd Gens for sure.
Then put it all back together. Be carefull pushing the shafts back in, there is a oil slinger type thing pressed into the inner ends of the axle tubes, if your careless pushing the shafts back in, you'll punch them out into the diff space.
After you have the wheels off, but before pulling the rest apart, pull the drums off and check the end float in the rear wheel bearing by pulling on the end of the axleshaft, if it has more than 1mm of play then you may want to do the bearings while its all apart. If you have any oil in the rear brakes, its also a sign the bearings are shot.
Its not an easy job without the right tools and a press, but the rear bearings tend to start showing signs of wear around 80-100k miles, and if they get to worn it smotherss the rear shoes with diff oil".
